Idaho Closing Costs Calculator: Estimate Your Buyer & Seller Costs

How to Calculate Closing Costs in Idaho

Closing costs in Idaho depend on the purchase price, loan amount, county, and which title company you choose. Unlike promulgated-rate states where everyone charges the same, Idaho is a filed-rate state (IDAPA 18.05.01) — rates vary by company and county, making calculation more nuanced but also creating savings opportunities.

Below is a step-by-step method to estimate your closing costs using real filed rates from the Idaho Department of Insurance.

Step 1: Determine Your County’s Escrow Rates

Idaho escrow rates are filed by each title company with the Idaho DOI. The 2025 Filed Short Term Escrow Rates show:

Ada County (Boise, Meridian, Eagle): $3.00 to $3.50 per $1,000. Nine companies — seven at $3.00, two at $3.50.

Canyon County (Nampa, Caldwell): $3.00 to $3.50 per $1,000. Ten companies — eight at $3.00, two at $3.50.

Bonneville County (Idaho Falls): $3.00 per $1,000. Five companies, all at $3.00.

Bannock County (Pocatello): $3.00 per $1,000. Five companies, all at $3.00.

Blaine County (Sun Valley, Ketchum): $1.50 to $2.00 per $1,000 — significantly lower than the rest of the state.

Step 2: Calculate Title Insurance Premiums

Owner’s policy (seller pays): Purchase price ÷ 1,000 × rate per thousand + base fee ($100–$150)

Lender’s policy (buyer pays): Loan amount ÷ 1,000 × rate per thousand + base fee ($100–$150)

Simultaneous issue discount: Subtract $100 when both policies are issued together

Example — $400,000 home, $320,000 loan, $3.00/thousand rate:

Owner’s: $400,000 ÷ 1,000 × $3.00 + $150 = $1,350. Lender’s: $320,000 ÷ 1,000 × $3.00 + $150 – $100 discount = $1,010. Title insurance total: $2,360.

Step 3: Add Recording Fees

Recording fees are set statewide by Idaho Code § 31-3205 — the same in all 44 counties:

Deed recording (buyer pays): $15. Mortgage/deed of trust (buyer pays): $45 for the first 30 pages, $3 per additional page. Mortgage release (seller pays): $15.

Step 4: Add Buyer-Specific Costs

Loan origination fee: 0.5% to 1% of loan amount. Appraisal: $400 to $600. Home inspection: $300 to $500. Prepaid items (taxes, insurance, mortgage interest): $2,000 to $4,000. Credit report: $30 to $50.

Step 5: Add Seller-Specific Costs

Real estate commissions: 5% to 6% of sale price. Owner’s title insurance: calculated in Step 2. Mortgage release recording: $15. Prorated property taxes: varies by closing date. Transfer tax: $0 — Idaho has no transfer tax at any level.

Complete Calculation Example

$400,000 purchase in Ada County, $320,000 conventional loan, $3.00/thousand title company:

Buyer costs: Lender’s title insurance: $1,010. Loan origination (0.75%): $2,400. Appraisal: $500. Inspection: $400. Recording ($15 + $45): $60. Prepaid items: $3,000. Buyer total: approximately $7,370 (1.8% of purchase price).

Seller costs: Owner’s title insurance: $1,350. Commissions (5.5%): $22,000. Mortgage release: $15. Prorated taxes: $1,200. Escrow share: $650. Seller total: approximately $25,215 (6.3% of sale price).

How to Reduce Your Calculated Costs

Choose a $3.00/thousand title company over $3.50 — saves $200+ on a $400,000 transaction. Ask for the reissue discount (up to 40% off the owner’s premium within two years per IDAPA 18.05.01.013). Negotiate seller concessions (up to 3% on conventional loans). Compare lender origination fees — these vary more than title rates.
